I posted this patch set as an RFC as I don't have time to waste on doing
more work, and I knew it would cause some controversy.

That said, this patch set does not yet add the plugins, but it lays the

could get plugins working with perf by next week. If we keep going in
this direction, otherwise, probably not till next year.
